Background Pigment dispersion syndrome (PDS) is a well-known entity which can lead to pigmentary glaucoma (PG). This case report presents a rare presentation of PG with bilateral dense pigment deposits of the posterior lens capsule. Case presentation A 72-year-old male came for his first appointment due to an asymmetric worsening of visual acuity. The examination showed unilaterally severely increased intraocular pressure, bilateral dense pigment deposition of the posterior lens capsule, and a shallow unilateral optic disk excavation. Gonioscopy revealed moderate pigmentation of the angle and a concave configuration of the peripheral iris in both eyes. The standard slit lamp examination showed no transillumination defects of either iris. Optical coherence tomography showed retinal nerve fiber layer (RNFL) thinning in the peripapillary and macular regions. An antiglaucoma medication was prescribed with a good lowering effect. Conclusion Pigment deposition of the posterior lens capsule, which has been rarely reported, is a possible important sign of PDS or PG.
Background: Multifocal intraocular lens (IOL) implantation is generally not considered in patients with keratoconus; however, it may provide good optical results in selected patients with stage I and II keratoconus based on two case reports. Aims: To evaluate patient satisfaction and clinical outcomes in this patient population.Methods: This is a retrospective single-center, non-interventional, non-comparison study. All patients with frank keratoconus who had undergone a trifocal IOL implantation between 2016 and 2019 were invited to participate in this study (18 eyes of 9 patients). Postoperatively, refractive outcomes, contrast sensitivity, and ocular aberrations were recorded. A questionnaire was used for determining patient satisfaction and their quality of life. The mean follow-up time was 31.22 ± 6.38 months.Results: Postoperatively the patients’ uncorrected distance visual acuity improved from 1.13 ± 0.93 to 0.10 ± 0.17 (p˂0.001), corrected distance visual acuity went from 0.10 ± 0.11 to 0.05 ± 0.09 (p=0.19), mean refractive spherical equivalent changed from -4.34 ± 4.31 to 0.05 ± 0.51 D (p˂0.001), and manifest astigmatism from 2.44 ± 1.92 to 0.88 ± 1.81 D (p=0.017). A target refraction of less than ± 0.50 D was achieved in 17 eyes (94%) and one eye exhibited a hyperopic MRSE of +2.0 D. Three eyes (17%) lost 1 line of best corrected visual acuity and no patient lost two or more lines. The patients were independent of glasses in 78% for all distances. Conclusions: A trifocal IOL currently gives relatively good, predictable results with most patients feeling satisfied with the results of spectacle independence for all distances.
Idiopathic orbital inflammatory disease, previously referred to as orbital pseudotumor, is a nonneoplastic, non-infective disease. The inflammatory process can involve one or more orbital sof tissues; extraocular muscles, tear gland, scleralorepiscleral tissue or orbital fat. Orbital myositis typically presents itself with a sudden onset of restricted ocular motility, diplopia, congestive proptosis, eyelid ptosis, periocular swelling and conjunctival hyperemia. A thorough workup is essential for ruling out other entities.This report presents a case of a 47-year old man with a sudden onset of right upper eyelid swelling and diplopia. Until then he had no health problems. Afer initial ophthalmologic workup and ultrasound an orbital mass was suspected. Te MRI and a biopsy of the mass confirmed an isolated superior oblique muscle myositis. We treated him with systemic steroids. A good response and fast regression were observed. In two years of follow-up visits no recurrence was noted.Isolated superior oblique muscle myositis is extremely rare. This is one of eleven cases documented between 1988 and 2015.

Ophthalmic complications of diabetes are one of the leading causes of visual loss and blindness in the working population worldwide. Globally, an estimated 422 million adults were living with diabetes in 2014. According to the World Health Organisation, this number will rise to an estimated 592 million by 2035. Cataract is a clouding of the eye lens. Surgery is indicated when cataract causes significant visual impairment. Several clinical studies have shown that cataract development occurs more frequently and at an earlier age in diabetic compared to nondiabetic patients. Cataract surgery is the most frequent ophthalmic surgical procedure and has an excellent outcome. However, diabetic patients may have more complications and a poor visual outcome. They are prone to ocular surface disease, intraoperative complications, corneal oedema in the early postoperative period and an increased incidence of cystoid macular oedema in patients with retinopathy. Anterior capsular contraction is also more frequent. A good prognosis is expected in patients with good systemic and ophthalmological preoperative, operative and postoperative management.
